Have you ever looked into stratigraphical studies for your geology class?

Not really, what’s interesting about them?

Root Explanation

Stratigraphical → It is formed from "stratum" (from Latin *stratum*, meaning layer) and "-graphical" (from Greek *graphikos*, meaning relating to writing or description). The word refers to the description or study of layers, particularly in geology.

Memory Tip

Think of 'layers' ('stratum') being described or studied ('-graphical') — that's what stratigraphical means.
